如何合并PrettyTable表中的列？ Python

如何解决如何合并PrettyTable表中的列？ Python

使用此代码：

from prettytable import prettytable
x= prettytable()
x.field_names = ["City name","Area","Population","Annual Rainfall"]
x.add_row(["Adelaide",1295,1158259,600.5])
print(x)

打印下一个：

+-----------+------+------------+-----------------+
| City name | Area | Population | Annual Rainfall |
+-----------+------+------------+-----------------+
|  Adelaide | 1295 |  1158259   |      600.5      |
+-----------+------+------------+-----------------+

我想要的是再添加一列，看起来像这样（我在 excel 中这样做只是为了说明）：

我尝试添加仅包含该值的行：

from prettytable import prettytable
x= prettytable()
x.field_names = ["City name",600.5])
x.add_row(["City No. 1"])
print(x)

但我收到一个错误：

edu@DESKTOP-0VFHRDP MINGW64 ~/Documents/tables (master)

    raise Exception(

如果你有其他想法，我愿意接受推荐。 感谢您的帮助。
